APPARATUS FOR HEATING AND CIRCULATING WATER.

SPECIFICATION forming part of Letters Patent No. 474,961, dated May 17,1892. Application filed December 3, 1891. Serial No. 413,851. (Nomodel.) 7

To all whom it may concern:

Be it known that we, HENRY A. JONES and JOSEPH E. MAROY, citizens of theUnited States, and residents of New York, in the county of New York andState of New York, have invented certain new and useful Improvements inApparatus for Heating and Circulating Water, of which the following is aspecification.

The object of the invention is to produce suitable apparatus connectedwith a kitchenrange whereby water may be heated and circulated throughradiators in the rooms of a dwelling or apartment for the purpose ofheating them, the design being to utilize the fire in the range forafiording heat to the rooms and to supply the hot water necessary fordomestic and toilet purposes; and to this end the invention consists inthe novel devices and combinations of parts hereinafter described andclaimed.

The invention will be fully understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which- Figure 1 is a front plan view, partly in section, of anapparatus constructed in accordance with the invention. Fig. 2 is anenlarged vertical section of same on the dotted line 2 2 of Fig. 1. Fig.3 is an enlarged View of the pipe connections below the boiler, and Fig.4 is a transverse section through the boiler on the dotted line 4 4 ofFig. 2.

In the drawings, A designates a kitchenrange of ordinary construction,except in that it is provided with the chamberB in the rear of itsfire-box C and with the coils 'D in said fire-box and forming awater-back. The coils D circulate along the sides and front and rearends of the fire-box O and afford an effective heating-surface for thewaterwithin them without interfering with the proper operation of therange for cooking and other purposes. The chamberB is in the nature ofan extension at the upper rear side of the range and is in line with thefire-box O, the chamber B and fire-box 0 being in connection with eachother 'and adapted to be cut off from each other when desired by meansof a hinged damper E, which is shown in its closed position by fulllines in Fig. 2 and in its open position by dotted lines. Within thechamber Bis supported by means of a rod F or other base thelower end ofthe boiler G,which, as more clearly illustrated in Figs. 2 and 4,consists of thecentral tubular portion H and the series of tubes I,encircling the portion [-1 and connected therewith at its upper andlower ends. The lower end of theboiler G is connected with the coils D,forming the waterback, and the upper end of said boiler is connectedwith a pipe J, through which the hot water passes to the radiators,bath, and such other places as it may be directed, as hereinafter moreparticularly stated. The boiler G,

consisting of the central tubular portion H and the tubes I, is inclosedby a shell or casing K, which rests upon the extension B of the rangeand is closed at its upper end by a cap L.

At one side of the casing or shell K there isa connection M with theordinary smoke pipe or flue N, provided with the usual damper O, asillustrated in Fig.1. The purpose of the connection M between the casingK and flue N is to permit the passage of the heat and smoke upwardthrough the casing K and around the boiler G, and thence through thepipe M into the flue N above the damper 0. When it is desired that theheat shall pass upward through the casing K prior to entering the flueN, the damper E will be opened and the damper 0 closed, and when it isdesired that the heat and smoke shall pass directly upward through theflue N and not affect the boiler G the damper E will be closed and thedamper 0 opened, under which condition of dampers the heat and smokewill take their usual course upward through the flue N.

The water used in supplying the water-back D will first be fed into thereservoir P, suitably mounted upon" a bracket or other support, thesupply-pipe for such reservoir being indicated by the letter Q, and thewater passes from said reservoir P through the pipe R, which at itslower end connects with the pipe S, which is in direct connection withthe inletpipe T of the coils D, and hence the water passing downwardfrom the reservoir P through the pipe R will enter the pipeS and pipe T,and thence pass directly into the lower coil D. The reservoir P is alsoprovided with an overflow-pipe V, which at its upper end above itsconnection with the reservoir P will preferably be open to theatmosphere. \Vitnin the reservoir P we recommend that an ordinaryfloat-valve be employed forthe purpose of closing off the supply fromthe pipe Q when the wa ter has attained its proper level, in order that'the operation of the apparatus may be automatic. The pipeJisconnectedwithamainsupply-pipe WV, which passes through the dwelling orapartment, and from it will extend to the various rooms, branch pipes Xdirectly connecting with the radiators Y and with the bath or toiletbasins or other places at which it may desired to have a hot-watersupply.

The radiatorsYwill also be connected at their lower portion with areturn-pipe Z, passing back to the vertical pipe S, connecting with thepipe T, leading to the coils D. It will thus be seen that there is acirculation of the water from the boiler G upward through the pipe J,pipe l/V, branch pipes X, radiators Y,

V culation, shall only be used in summertime,

when it may be desired that hot water is only wanted for use in thekitchen, and at such time the valve d will remain open, in order thatthere may be a free circulation of water from the pipe J downward intothe heatingcoils D, forming the water-back. In winter, however, when itis desired to have the rooms heated by the radiators Y the shortcirculation through the pipes Ct b will be prevented by closing thevalve d.

In order that the kitchen may be provided with a ready means of drawingthe hot water for domestic purposes, the pipe 6 is provided, which, asillustrated in Fig. 1, extends from the upper end of the pipe J to thepipef,leading downward to the sink g and provided with the usual fauceth. The upper end of the pipef passes upward beyond the pipe 6 and entersthe upper end of the reservoir P, where it operates as an air-escape.

We have described above all of the pipe connections necessary for theheating and circulation of the water, and but one additional pipe needbe employed and that is for drawing off the water from the apparatus. InFig. 1 we have illustrated this pipe as leading from the vertical pipe0. to the sewer-pipe 1' and have indicated the same by letter j. Thispipe j may of course be led to any source; but we prefer to connect itdirectly with the pipe 1' and to provide it with a valve 7r, by which itmay be closed, except at such times as it may be desired to draw off thewater.

In the operation of the invention cold water may be supplied through thepipe Q to the reservoir P, whence it will pass downward through the pipeR into the pipesS T and enter thecoils D, where it will be heated andcaused to pass into the boiler G and upward through the pipe J, whenceit will be circulated through the pipe "W, branch pipes X, radiators Y,and return-pipe Z, thus moving the water to the pipes S T and again intothe heating-coils D. At the same time the hot water may be drawn at thesink g by means of the pipe 6, pipe f, and faucet h. The damper E beingopen and the damper 0 closed, the entire heat escaping from the fire-box0 will pass upward around the tubular portion H,

encompassing the tubes I of the boiler G, and

thus effectually increase the heat of the water prior to its escapethrough the pipe J and pipe W.

It is to be understood that each of the radiators Y throughout thebuilding will be provided with an independent valve m, by which thewater may be turned off or on, and hence should it not be desired toheat a portion of the rooms such rooms may be removed from the effect ofthe hot water, and it is also to be understood that in summertime thepipe leading to the bath may remain in complete con nection with theboiler G, thus being supplied with hot water, while the remaining roomsof the dwelling will be unaffected by the circulatingwater. Thereservoir P also operates as an expansion-tank,and hence the heat doesnot expand the water back into the main nor interfere with thecold-water faucet. The water flows from the expansion-tank to theheating-coils D by gravity.
